Erste Charakterisierung eines nichtneutralen Plasmas bei toroidalem Magnetfeldeinschluss
- Gabor lenses were invented for focusing hadron beams by the electric field of a confined electron column. A homogenous magnetic field created by a solenoid confines electrons in transverse direction while a potential well created by a cylindrical electrode system confines them longitudinally. In this thesis the investigation and characterization of a nonneutral electron plasma (NNP) in a Gabor lens with a toroidal magnetic confinement and a 30 degree-bent anode is presented. Motivated by fundamental research on NNPs in this special environment, diagnostic methods were investigated to characterize the plasma. As a non-invasive method a PCO camera is placed in front of the experimental setup. A ring of 31 photodiodes is used inside the plasma for light intensity and distribution measurements. The experimental data is evaluated and the following results will be presented.
